Solution

====================
RELEASE DEPENDENCIES
====================

-- You can use a single LiveUpdate server for NetBackup to deploy updates for UNIX and Windows.
To create a LiveUpdate server for NetBackup Windows 7.5.0.4, you must download and extract the following bundle(s).

You only need to extract the bundles for the windows platforms you plan to update.

NBLU_7.5.0.4.WINx64.zip
NBLU_7.5.0.4.WINx86.zip

-- You can use the same LiveUpdate server to deploy NetBackup updates for UNIX.
To accomplish this, you must download and extract the bundles into the same location as the NetBackup Windows bundle(s).

-- In order to update NetBackup UNIX hosts, be sure that /tmp on the hosts to be updated meet the minimum available space requirements of 4.0GB for NetBackup Servers and clients.
See the Known Issues section below for more information.

Creating a LiveUpdate Server for NetBackup:
-------------------------------------------
A LiveUpdate Server for NetBackup does not require any additional software, but is simply an HTTP server or disk share that has been populated with the contents of this
LiveUpdate Server for NetBackup bundle.

1. Create a LiveUpdate Server for NetBackup.
a. Configure either an HTTP server or a shared disk that can be accessed by all NetBackup hosts that you plan to update. Refer to the 7.5 "NetBackup LiveUpdate Guide."

The LiveUpdate Server for NetBackup can be a Windows or UNIX host. NetBackup LiveUpdate policies can be used to update NetBackup on either Windows or UNIX machines.

b. Download the following file(s) into the root directory of the NetBackup LiveUpdate server, which is either the HTTP root directory or the shared disk directory.

NBLU_7.5.0.4.WINx64.zip
NBLU_7.5.0.4.WINx86.zip

You only need to extract the bundles for the windows platforms you plan to update.

2. Extract the following file(s) into the root directory of the NetBackup LiveUpdate server, which is either the HTTP root directory or the shared disk directory.

NBLU_7.5.0.4.WINx64.zip
NBLU_7.5.0.4.WINx86.zip

a. To extract the bundle(s) on a Windows system, use an appropriate unzip utility.

b. To extract the bundle(s) on a UNIX system, use the following command.
Determine if your UNIX system has "unzip", otherwise you will need to obtain a version compatible with your UNIX system.

unzip NBLU_7.5.0.4.WINx64.zip
unzip NBLU_7.5.0.4.WINx86.zip

This creates a large number of files that comprise a LiveUpdate Server for NetBackup. Do not rename, move, or delete any files that were extracted.

NetBackup LiveUpdate Known Issues:
----------------------------------
The following issues pertain specifically to the LiveUpdate server for NetBackup product.

+ (ET1544083) When creating a LiveUpdate policy, make sure that the policy name is unique and that it is not the same as any other internal or external
policy name. The LiveUpdate policy fails if its name is the same as any other policy name.

+ Currently, when a client is configured to use a UNC for the LiveUpdate server, and the update is launched using the policy execution on the
LiveUpdate server, the nbliveup process on the client starts and then halts shortly after starting.

This is the result of system permissions and the local SYSTEM account's inability to resolve network drives. Refer to the following TechNote on the
Symantec Support Web Site for more information.

+ If you are updating a clustered NetBackup server in a VCS configuration, Symantec recommends that you run the manual patch install.

+ In order to free up disk space for downloading updates, the JavaLiveUpdate agent on UNIX caches downloaded patches, by default, in the /tmp directory.

To reconfigure the directory the JavaLiveUpdate uses for temporary space, modify the "workdir" setting in the /usr/openv/netbackup/nblu.conf file.

+ In order to successfully use LiveUpdate to apply NetBackup 7.5.0.4 on UNIX hosts, ensure the total available space in the /tmp directory of the
NetBackup host to be updated meets the following minimum space requirement:

NetBackup Server - /tmp must have at least 4.0GB of total available space
NetBackup Client - /tmp must have at least 4.0GB of total available space

If the /tmp directory of the NetBackup host to be updated cannot meet the minimum requirement, you can reconfigure the JavaLiveUpdate agent to use an
alternate directory. Edit the "workdir" setting in the /usr/openv/netbackup/nblu.conf file. For example, to reconfigure a machine
to use /space/downloads as the working directory, edit nblu.conf to replace the line:

workdir=/tmp

With the following line:

workdir=/space/downloads

Failure to meet the minimal space requirement can result in your NetBackup Liveupdate policy failing with an exit status of 77. The
/opt/Symantec/LiveUpdate/liveupdt.log will indicate exit status "246", with a message similar to the following:

Uninstalling NetBackup Maintenance Release 7.5.0.4:
---------------------------------------------------
LiveUpdate for NetBackup does not provide a NetBackup policy method for uninstalling Maintenance Releases.
You must follow this procedure locally on each NetBackup host that you want to uninstall.

To uninstall the Maintenance Release from a Windows CLUSTER Environment:

1) Uninstall this Maintenance Release from the nodes of the cluster where the NetBackup group is inactive. (follow steps 1-2 below)

2) Uninstall this Maintenance Release from the active NetBackup node.
This should be done when the NetBackup system is quiet, for example, no backups or restores running.

CAUTION:
Do not fail over the NetBackup Group until all NetBackup nodes (including the active NetBackup node) have the Maintenance Release uninstalled.

**Important notice regarding un-installs on Windows**
Only the last Maintenance Release installed on a Windows system can be un-installed.

1) Close all NetBackup Windows. Make sure the NetBackup server has no active backups, restores,
duplications, etc., running. If there are NetBackup activities in process, the Maintenance Release will not install if the file to update is busy.

If a database client is being used, such as Oracle, ensure that the database services are stopped. Database services can be stopped via the
Control Panel -> Services tool. Repeat this until all databases have been stopped. These services must be restarted once the patch is successfully uninstalled.

2) Go to Add/Remove programs dialog box and select the correct Maintenance
Release to be uninstalled.

WARNING: While the Maintenance Release is being uninstall, any attempt to cancel the uninstall operation while it is in progress might leave NetBackup
in an unknown state. Once you have canceled the uninstall, you should manually try to restart the services. If the services do not come up
properly, Symantec recommends that you completely uninstall the Maintenance Release and install it again.
